Title: Device and method for displaying stereoscopic image
Inventor: MIYAZAKI MAKOTO
IPC: H04N13/04
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To display a stereoscopic image without a sense of incongruity while executing gradation control by changing a time division pattern in accordance with scanning of a screen. SOLUTION: At the first scanning, the state of a pixel is turned on only for a corresponding period in an order from a bit B7 to a bit B0 but at the second scanning, the state of the pixel is turned on only for a corresponding period in an order from the bit B0 to the bit B7. After then, at the odd- numbered scanning, a gradation pattern is similar to that at the time of the first scanning but at the even-numbered scanning, the gradation pattern is similar to that at the second scanning. As long as the screen is scanned in a fixed direction by gradation control like this, a light area and a dark area no longer appear normally in a pixel passing area. Namely, the pixel passing area becomes a continuous area in brightness of some degree. As the result, a stereoscopic image being the set of the pixel passing areas becomes an image free from flicker and becomes natural for an observer.

Inventor: MIYAZAKI TSUTOMU
IPC: H02M7/537
Filed: 1993-02-26
Abstract: PURPOSE:To allow induction heating of a work disposed in a heating coil closely thereto by operating a single transistor as a current regenerating inverter for inducing high frequency current in the secondary coil of a transformer. CONSTITUTION:A transistor drive circuit 6 turns a transistor 7 ON/OFF to feed a resonance current of a capacitor 9 and the primary coil 4a of a transformer 4 thus inducing an AC high frequency current in the secondary coil 4b of the transformer 4. The high frequency current is fed to a heating coil 12 for induction heating a work 13. In this regard, current flowing through the circuit is detected by means of a resistor 11 and fed to a transistor drive circuit 6 in order to control the output to a predetermined level. This constitution allows reduction in the size and weight of a transistor inverter unit 1 and further downsizing is realized by employing an IGBT 5 comprising moduled transistors 7 and diodes 8.

Title: Load drive circuit
Inventor: MOKUYA HIROBUMI
IPC: H01L23/58
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To realize fuseless protection of a load circuit against overcurrent. SOLUTION: An intelligent power device IPD 10 having a temperature- sensitive protective function is employed as a semiconductor element for driving a load 2 and the sensing temperature thereof is set depending on the allowable load current. More specifically, a relationship TSD=I<2> ×RON×RTEMP+TROOM is set, where RON is the ON-state resistance of a power MOSFET 11, TROOM is the ambient temperature of the IPD 10, RTEMP is the thermal resistance of the entire heat discharge system of the IPD 10, I is an allowable current level, and TSD is the sensing temperature. Since a sensing temperature is set depending on the allowable load current, the IPD 10 stops load current supply at a sensing temperature when the load current reaches an allowable level thus protecting a load circuit against overcurrent.

Title: Gas laser device
Inventor: OKAMOTO NOBORU
IPC: H01S3/097
Filed: 1987-03-18
Abstract: PURPOSE:To conduct pre-ionization with high efficiency, and to oscillate laser beams having a high output by positioning the gaps of pre-ionizing electrodes between a cathode and an anode and near the discharge surface of the cathode. CONSTITUTION:Gaps are formed at the central level of a discharge space section 4 in pin electrode pairs 12, and gaps are shaped at the level of the discharge surface 3a of a cathode 3 in pin electrodes 13. The electrode pairs 12 and 13 are faced oppositely, and disposed alternately on both sides of the longitudinal directions of an anode 2 and the cathode 3. Consequently, a laser gas in the discharge space section 4 is irradiated uniformly with ultraviolet rays in the iongitudinal direction and the cross direction. Since energy photoionizing the cathode 3 is smaller than that photoionizing the laser gas, pre-ionization is performed effectively by smaller energy and main discharge is stabilized, thus oscillating laser beams having a high output.

Title: Electrophotographic sensitive body
Inventor: NAGAME HIROSHI
IPC: G03G5/082
Filed: 1988-03-18
Abstract: PURPOSE:To suppress the instability of a surface potential when the photosensitive body is repeatedly used and to improve the electrostatic chargeability thereof by consisting said body of 3 layers; a 1st As-Se layer, As-Se-Te layer and 2nd As-Se layer successively from a conductive base side and forming a barrier layer further thereon. CONSTITUTION:The As-Se layer 2, the As-Se-Te layer 3, the As-Se layer 4, and an intermediate layer 5 are successively formed on the conductive base 1 and such a barrier layer 6 which prohibits the injection of positive charge to the As-Se layer 4 is formed on the contact surface of the intermediate layer 5 and the 2nd As-Se layer 4. A protective layer 7 is formed on the extreme surface. The electrostatic charge potential is thereby stabilized as compared to heretofore even if the concn. of Te in the As-Se-Te is changed by the fluctuation in vapor deposition and materials. The potential fluctuation arising from repetition is thus decreased and the change in image density arising therefrom is lowered as well. Since there is an allowance in the charge potential, the charge current is kept low and an allowance is given to a power supply as well.

Abstract: PURPOSE:To improve recording and reproduction efficiency, to eliminate contour effect, and to prolong the life of a head by providing one block with a winding part in a thin-film process and joining two blocks so that metallic magnetic films form recording tracks. CONSTITUTION:The metallic magnetic films 12 are formed on mountain-shaped projection parts 11 of two substrates 1 made of non-magnetic materials, and the core blocks are joined across a gap material 13 by using a joining material 16.
